This paper takes the filling beverage and food purification workshop as the starting point, and analyzes what matters and construction requirements need to be paid attention to in the design and construction of the food 100,000 QS purification workshop according to the current standards and specifications, so as to meet the food production enterprises (companies) with reasonable production process, advanced scientific production procedures, perfect quality control and strict operating procedures and finished product quality management system. Provide reference.
First, plant building requirements
1, the buildings of the plant should be durable, easy to maintain, easy to clean, and can prevent food, food contact surface and internal packaging materials from contamination (such as the invasion of harmful animals, habitat, reproduction, etc.) structure.

2, in order to prevent cross-contamination, personnel channels and material transport channels should be set up respectively, and each channel should be equipped with air curtains (namely wind curtains) or two-way spring doors and electronic fly (mosquito) devices and other insect control facilities.
3, it is necessary to completely fill the gap around the pipeline, doors and Windows and ventilation channels leading to the outside world, and all Windows, vents and fan openings should be installed with protective nets.
4, the height of the production plant should be able to meet the process, health requirements, as well as equipment installation, maintenance, maintenance needs.
2. Ground and drainage
The ground should be paved with non-toxic, non-permeable, non-absorbent, non-slip, non-crack and easy to clean and disinfect building materials (such as acid-resistant brick, terrazzo, concrete, etc.), and the ground should have an appropriate slope (1.0~ 1.5% is appropriate).

3. Roof and ceiling
1. The roof and ceiling should be coated or decorated with light-colored materials that are non-absorbent, smooth, non-toxic, mildew resistant, corrosion resistant and easy to clean, which can reduce the effect of condensation and dripping in structure.
2, food and food contact surface exposed above should not be equipped with steam, water, electrical and other auxiliary pipes, to prevent dust or condensed water fall into.
Walls and doors and Windows
1. The walls of the production workshop should be constructed with light-colored materials that are non-toxic, non-absorbent, non-permeable, mildew resistant, smooth and easy to clean, and the height of decoration with this material should be up to the roof.
2. All doors and Windows should be sealed with rust-proof, moisture-proof and easy-to-clean frames.
5. Lighting and lighting facilities
The workshop should have sufficient natural lighting or artificial lighting, the mixed illumination of the working surface of the processing site should not be less than 300Lx, and the batching and filling workshop should not be less than 800Lx.
Six, air purification equipment measures
1, the workshop must be installed effective ventilation equipment, the air flow should flow from clean areas to non-clean areas, the use of mechanical ventilation, ventilation should be greater than 3 times/hour. Install ozone generator disinfection equipment for sterilization
2. The temperature of the clean workshop should be controlled between 15 and 27 ° C, and the humidity should be controlled below 50%.
3, the entrance of the clean workshop should be equipped with air shower purification facilities for personnel and materials.
